MINING-DRILL AND CHANNEL-CUTTER.

SPECIFICATION forming part of LettersPatent No. 597,358.9, datedr'anuary 18, 1898.

Application filed November 80, 1896. Serial No. 613,922. (No model.)

To all whom it may concern.-

Be it known that I, JOHN PHILLIP PAYN- TER, of Topeka, in the county of Shawnee and State of Kansas, have invented a new and Improved Mining-Drill and Channel-Cutter, of which the following is a full, clear, and exact description.

The invention relates to mining-drills and channel-cutters such as shown and described in the Letters Patent of the United States, No. 395,716, grant-ed to me on January S, 1889.

The object of the present invention is to provide a new and improved mining-drill and channel-cutter arranged to cut a narrow opening or slot in the seam or underneath 5o as indicated in Fig. 1.

the coal and remove lthe cuttings from the seam to enable the miner to easily wedge or break down the coal above.

Theinvention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference in dicate corresponding parts in all the iigures.

Figure l is a plan View of the improvement. Fig. 2 is a front end elevation of the'same as applied. Fig. 3 is a rear side elevation of the improvement, with part in section. Fig. 4 is an enlarged sectional side elevation of the drilling-tool. Fig. 5 is a transverse section of the same. Fig. 6 is an enlarged side elevation of the conveyer, with part in section; and Fig. 7 is an enlarged side elevation of the `reversing mechanism for the engine.

The improved machine is provided with a suitably-constructed frame A, provided at each end and near one side thereof with vertically-disposed pulleys B, engaging opposite sides of a tube C, extending longitudinally in the mine and forming the track for the said framel A to travel on, said tube also forming a supply-tube for furnishing the engine E on the said frame A with compressed air as the mot-ive agent for actuating the engine, the tube C being for this purpose connected by a flexible tube D with the engine, The tube C thus stands under one side of the frame A, said tube forming a fulcrum for the said frame for swinging the latter up and down in a transverse direction, the free end of the frame being supported by a pulley B', adapted to travel in the undercut or channel and journaled on a transverselyeXtending pin B2, projecting from an arm B3, secured on a transversely-extending sh aft B4, journaled in suitable bearings on the free end of the frame A. (See dotted lines in Figs. l and 3.) The inner end of the shaft B4 carries a worin-wheel B5, in mesh with a Worin B6, secured on a shaft B7, disposed vertically and journaled in suitable bearings in the frame A. -On the upper end of the shaft B7 is secured a ratchet-Wheel BS, in mesh with a pawl B9, secured on a lever B10, extending horizon tally and fulcrunied on the said shaft B7. The lever B10 is under the control of the operator to enable the latter to move the lever forward and backward and impart an intermitteilt rotary motion to the shaft B7 by the pawl B9 and ratchet-Wheel B8. The rotary motion of .the shaft B7 is transmitted by the Worm B6 and Worm-Wheel B5 to the shaft B4, so that the arni Bg thereon is swung up or down, and consequently the pulley B is raised or lowered to impart an up-and-down swinging motion to the frame A as the pulley travels on the bottom of the undercut or channel.

The engine E previously mentioned is preferably made With two cylinders connected in the usual manner with the main driving-shaft E', on which is secured a gear-wheel lhin mesh with an intermediate gear-Wheel F', secured on the shaft F2,`journaled in suitable bearings on the frame A. The gear-wheel F is in mesh with a pinion G', secured on a transversely-extending shaft G, journaled in suitable bearings in the frame A and supporting at its outer end the drill-tool Il, extending from the free end of the frame A, as is plainly shown in Figs. l and 2. Thus when the engine is set in motion the rotary motion of the shaft E' is transmitted by the gear-wheels F, F', and G' to the shaft G, and by the latter to the drill-tool H, so that the latter rotates and at the same time moves longitudinally with the frame A.

The drilltool H (shown in detail in Figs. 4 and 5) is made conical and formed with a thread H', from which extend cutters H2 in a radial direction, said cutters being securely ICO held in place by set-screws H2 or other suitable means. Each cutter H2 has its shank fitted into an aperture H4, formed radially in the drilling-tool, and opposite this aperture is arranged another radial aperture H5 for the introduction of a tool for driving out the cutterA H2 whenever it is desired to remove the same for repairs or replacement. It is understood that the said set-screw H3 is loosened when it is desired to remove the cutter,as above mentioned. The drill-tool is also provided with a longitudinally-extending bore or aperture H, into which open the oppositelyarranged apertures H"l H5.

Directly in the rear of the drilling-tool H is arranged a transversely-extending conveyer I, formed with a spiral blade forremoving the cuttings produced by the d rilling-tool H out of the undercut or channell The inner end of the conveyer I is secured on a shaft J, (see Fig. 6,) journaled in suitable bearings in the main frame and carrying a gear-wheel J', in mesh with a gear-wheel G2, secured on the shaft G, so that when the latter is rotated, as previouslyv explained, arotary motion is transmitted by the gear-wheels G2 and J' to the shaft J and to the conveyer I.

The inner end of the conveyer I discharges the cuttings upon a conveyer belt or chain K, which passes over a sprocketwvheel J 2, formed on the end of the shaftJ, the conveyer chain or belt extending longitudinally in a rearward direction to pass over a pulley K', journaled at the rear end of the frame A. Thus the cuttings delivered to the chain or belt are removed rearwardly and discharge at the end of the frame in the shaft.

In order to impart a forward traveling motion to the frame A, I provide a chain L, eX- tending longitudinally and secu red at its forward end to a screw-rod N, held on a bracket O, secured in the end of the mine-shaft. The chain L extends iirst under a guiding-pulley P, to then pass around a pulley P', journaled loosely on the free side of the frame A, (see Figs. l and 3,) the chain then passing around a pulley P2, to then extend rearwardly. The pulley P2 is secured on a shaft P2, journaled in suitable bearings on the main frame A, and on the said shaft is fastened a sprocketwheel Q, in mesh with a pinion Q', attached to a transversely-extending shaft Q2, journaled in suitable bearings on the frame A. (See Figs. l and The forward end of the shaft Q2 carries a worm-wheel Q3, in mesh with a worm Q4, secured on a longitudinallyextending shaft Q5, journaled in bearings on the top of the frame A. On the shaft Q5 is secured a beveled gear-wheel Q6, in mesh with a beveled gear-wheel Q7, secured on the shaft F2,carrying the intermediate gear-wheel F', as previously described.

When the engine is in motion and the pinion F rotates the gear-wheel F' and its shaft F2, then the motion of the latter is transmitted by the beveled gear-wheels Q7 Q6 to the shaft Q5, which by the worm Q4 and the motion of the latter is transmitted by the pinion Q' and the gear-wheel Q to the shaft P3 v to revolve the pulley P2 and cause the latter to travel on the chain L, fixed at one end to the screw-rod end of the bracket O. Thus the frame A is drawn forward, traveling on the tube C, with the pulleys B' resting on the ground of the cut.

The operation is as follows: lVhen the parts are in the position illustrated in Figs. l, 2, and 3 and the motive agent is admitted from the tube C and pipe D to the engine E, then the latter is set in motion and causes a forward feeding of the frame, as above described, by the action of the pulley P2 on the chain L and at the same time a rotary motion is given to the drilling-tool H, so that the cutters H2 thereof cut the material and form an undercut or channel. The cuttings left by the drilling-tool in the undercut are moved trans` versely in an outward direction by the conveyer I, which discharges the cuttings upon the longitudinal belt or chain K, so that the cuttings are discharged outside of the under.- cut in the mine-shaft at the rear end of the frame. Thus when the frame A arrives at the end of its travel an undercut or channel is produced free of cuttings, which enables a miner to easily wedge down the coal above.

The frame A may be run in either direction, and for this purpose I provide the engine with the reversing mechanism shown in Fig. 7. On the shaft E' of the engine is secured a sleeve E2, on which is mounted to rotate loosely an eccentric disk E2, carrying an eccentric-strap E4. From the face of the eccentric disk E3 projects a pin E5, adapted to engage either of the two recesses or lugs E6 ET formed on the sleeve E2. The disk E3 is also provided with apertures E2, adapted to be engaged by a suitable wrench or other tool for conveniently turning the said disk E3 and engaging the ,pin E5 with either of the recesses or lugs E6 E7. As the latter are arranged diametrically opposite each other, it is evident that the half-turn given to the disk E3 reverses the position of the eccentric to reverse the engine.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. Arock-cuttingdevicehavingacombined air-supply pipe and rail, an air-operated motor and flexible connections between the combined pipe and rail and the motor, substantially as described.
